SDM72DM
THREE PHASE ENERGY METER
SDM72D-M is RS485 Modbus Din Rail Three Phase Multi-function Energy Meter.
The unit measures and displays voltage, current, frequency, power factor, active power, reactive power, active energy and reactive energy, etc. A resettable partial energy is provided, so the user can easily check the active energy imported and active energy exported during a certain period.
The meter has been assessed and certified as meeting the requirements of EU Directive 2014/32/EU. The instrument tracebale number is 0120/0213.
